Title: Sensing movement about a plurality of axes
Inventor: WING WILLIS GUY
IPC: H01S3/083
Filed: 1967-06-08
Abstract: 1,143,033. Optical navigation. SPERRY RAND CORP. 8 June, 1967 [13 June, 1966], No. 26488/67. Heading H4D. In apparatus for sensing movement about a plurality of axes, e.g. three orthogonal axes, comprising a plurality of ring lasers 40, 41, 42 (42 out of sight), each mounted to be responsive to rotation about a respective one of said axes and having an output F 1 , F 2 , F 3  representing said respective rotation, each of said ring lasers has contra-rotating light beams tending to have a threshold below which the laser output is not proportional to sensed rotation and common rotational biasing means 54 is thus provided for simultaneously biasing all of said lasers whereby the contra-rotating beams always exceed said threshold and said proportional representation is maintained. A ring laser comprises an arrangement of laser gas discharge tubes optically connected in series by mirrors to form a closed path whereby two contra-rotating light oscillations are established in the closed path. The two oscillatory frequencies are equal if the ring laser is stationary with respect to an inertial frame, but commence to diverge in opposite directions when the ring laser is subjected to a rotation in its plane. Said divergence can be determined by an optical mixer and is proportional to said rotation for values of rotation above a threshold below which interference between the two beams occurs and the divergence drops to zero. A " bias " rotation is thus given to the ring laser such that it operates in the linear part of of its output characteristic, Fig. 2. The three ring lasers 40, 41, 42 (comprising three laser tubes and three mirrors) are mounted on the respective faces of a comer of a cube and the rotational bias is applied about an axis coincident with the diagonal comer to corner line of the complete cube. Equal components of this rotational bias occur for each ring laser. The frequency divergence signals F 1 , F 2 , F 3  are fed to a digital computer 43 to give position information and to frequency dscriminators 44, 45, 46 which produce D.C. signals indicating the deviations from a desired frequency divergence F 0 . Diodes 47, 48, 49 and negative source 51 cause the most positive discriminator output, corresponding to the lowest frequency divergences, and thus that nearest to the threshold value, to be applied to rotational bias drive 54, in such a sense that the bias is increased to take said lowest frequency divergence away from the threshold. The change in the rotational bias is fed to the computer. Accelerometers 60, 61 and 62 are also provided, feeding their outputs to the computer.

Title: Improvements in or relating to explosives suitable for coal blasting
IPC: C06B31/56
Filed: 1939-09-28
Abstract: 535,137. Explosives. DU PONT DE NEMOURS & CO., E. I. Sept. 28, 1939, No. 26809. Convention date, Sept. 28, 1938 [Class 9 (ii)] A process for making a granular detonating explosive especially suitable for coal blasting, comprises mixing ammonium nitrate with a solid detonation sensitizing agent capable of serving also as a binding agent, and a liquid for softening the sensitizing agent, the mixing being effected without destruction of the individual identity of the component materials, the resultant particles being compacted and granulated, all particles being eliminated which pass a 50-mesh sieve. As the binding agent for holding together the particles of ammonium nitrate and other ingredients, to form the distinct granular explosive units, there may be employed a combustible material capable of gelatinization in the presence of a volatile solvent and preferably the binding agent will also act as a good sensitizer for the ammonium nitrate, for example, nitrocellulose, ground smokeless powder, polyvinyl nitrate. Binding agents without sensitizing action such as starch, ethyl cellulose, and polyvinyl acetate may be used in conjunction with a non-binding sensitizing agent. The binding agents are rendered adhesive by a volatile solvent such as acetone, amyl acetate, methyl alcohol and other solvents having sufficiently low boiling points to permit their ready removal. Additional oxydizing agents such as sodium nitrate, potassium nitrate, barium nitrate, potassium chromate, manganese dioxide, and additional combustible ingredients such as wood pulp, starch, various meals and salts of organic acids may be included. The ammonium nitrate used is preferably of such size that not less than 40 per cent will pass through a 48-mesh screen, and the total amount of ammonium nitrate is preferably 75-85 per cent of the explosive.

Title: Improvements in and relating to catalytic reforming of gasolines
IPC: C10G59/02
Filed: 1953-10-05
Abstract: A process for the catalytic reforming of gasolines containing less than 35 per cent by weight of naphthenes comprises conducting the gasoline in a first stage over a platinum catalyst on a carrier consisting of or containing aluminium oxide, together with at least 500 litres of hydrogen per Kg. of the gasoline, at a pressure of at least 20 atmospheres at 470-530 DEG  C., separating a fraction boiling within the boiling range of gasoline and passing this fraction together with not more than 500 litres of hydrogen per Kg, the amount of hydrogen employed being such that the molar ratio of the hydrogen present to the hydrocarbons is less than 3 : 1 over a regenerable cyclization catalyst comprising a metal or a compound of a metal of Group 5, 6 or 8 of the Periodic Classification, under a pressure of not more than 20 atmospheres at 490-550 DEG  C. and at a rate of not more than 2 Kg. of said fraction per litre of catalyst per hour.  In an example, a gasoline fraction boiling at 121-196 DEG C. having an aromatic content of 17 per cent by weight, and a naphthenes content of 27 per cent by weight was fed at 2 Kgs. per litre of catalyst per hour in the presence of 1500 litres of a gas mixture which contains 83 per cent by volume of hydrogen, per Kg. of the gasoline, over a commercial platform catalyst at 50 atmospheres at 485 DEG  C.  A fraction consisting of pentane and higher boiling hydrocarbons and having an octane number of 71 was passed with 100 litres of hydrogen per Kg. over a Cr2O3-Al2O3 catalyst under 5 atmospheres at 520 DEG  C.  The resulting reformate had an octane number of 80. The regenerable catalyst may be of the molybdenum oxide, chromium oxide and platinum types.

Title: Improvements in or relating to controlling means for metal-rolling mills
IPC: B21B39/04
Filed: 1936-10-07
Abstract: 463,928. Rolling. SCHLOEMANN AKT.-GES. Oct. 7, 1936, No. 27268. Convention date, Nov. 1, 1935. [Class 83 (iv)] Relates to rolling-mills in which the arrangements previously used for such control of rolling mills comprised work actuated switches, light sensitive cells or a current of air, interrupted by the work to increase its pressure and so actuate the required mechanism, or mechanism actuated by a change in the pressure of the work on the rolls, these arrangements being replaced by a vibration control 10 actuated by the vibration set up by the work which is used to actuate the control required for any part of the mechanism, e.g. the pass adjustment or the work lifting table 3. A sheet entering the rolls from the left causes a shock which is propagated to the vibrator 10 thus closing contacts 11 whereby the relay A closes contact a<1> and a<2> whereby a<1> excites the time delay relay B which keeps itself closed by contacts b<1> which have no time lag, while after a delay the contact b<2> also closes. While the sheet is proceeding through the rolls the vibrator 10 opens its contact 11 until the shock of the sheet leaving the rolls again closes the contacts 11 again actuating relay A so that current is supplied through a<2> and the previously closed b<2> to the relay F, so that f and f<2> are closed and f<3> is opened f<1> completes the exciter winding 8 to close clutch 6 whereby the table 3 is raised by the motor 5 and crank rod 4. f<2> closes a holding circuit for the relay F so that f remains excited even after the shock of the work leaving the rolls has died away. f<3>being opened de-energizes the relay E and with it also, owing to the opening of e<1> the exciter winding 9 to release the brake 7 and allow the table to be raised. At the top position of the table 3, the crank actuates a limit switch D to open d<1> and d<3> and close d<2>. d<1> being opened interrupts the holding circuit for relay B and d3 being opened interrupts the holding circuit for the relay F, thus declutching the motor 5 and applying the brake 7 to the table mechanism. When d<2> is closed, the relay C after an adjusted time lag, to allow the sheet to pass from the table over the top of the mill, closes c<1> to initiate the same switching as before, but to lower the table 3 for a fresh cycle of operations.
Patent GB-408308-A (GB)
Title: Improvements in or relating to clutch operating mechanism for motor vehicles
IPC: B60K23/02
Filed: 1932-10-01
Abstract: 408,308. Operating motor - vehicle clutches. BORG & BECK CO., 6558, South Menard Avenue, Chicago, U.S.A. Oct. 1, 1932, No. 27342. Convention date, Dec. 1, 1931. [Class 80 (ii).] In engine-suction servomotor gear for operating motor - vehicle clutches, wherein the regulator-valve mechanism comprises a driveroperated main valve, a check valve to cut off inflow of air when the clutch members initially contact, and a " bleed " opening controlling the final engaging phase, the rate of " bleed " into the suction side of the servomotor is so varied by a valve automatically actuated by the engine suction as to be inversely proportional thereto. Further, the suction side of the servomotor is sealed by the valves from atmosphere and the intake manifold at the check point so as to hold the clutch elements arrested until a voluntary action permits their resumed motion under restraint of the " bleed " opening. The servomotor comprises a chamber 15 with a flexible diaphragm 19 and rod 27 cableconnected to the clutch pedal 42, the main valve 57 being connected by linkage 83, 85, 89, rockshaft 88, arm 91, ball-jointed link 92, and rockshaft 79, carried in a swivelling bearing 78, to a crank 81 carrying a roller 82. A treadle 73 is so mounted by hinges 75, 76 that depression of its lower end raises the valve 57 against a torsion spring 90<1>, while depression of its upper end independently operates the button 72 of the accelerator rod 71. When the valve 57 is raised, its lower piston 59 meshes ports 53, 55 in the valve casing 51 and its upper piston 58 puts the chamber 15 into communication with the inlet manifold 12 by way of pipes 98, 96, 56 and the space around the valve stem 60, so that the rod 27 is lifted and the pedal 42 rapidly depressed. On release of the valve 57, the pipe 56 is connected to atmosphere by way of the port 53 and a port 66 in a check-valve casing 52, the check valve 65 having been raised at this time to uncover both ports by adjustable connections 69, 47 with the rod 27. Thus, at a predetermined point in the descent of the rod 27, the ports 53, 66 are covered by the valve 65, and its further movement is checked. If now the throttle is opened, the increased pressure in the manifold 12, communicated by a pipe 100 to a chamber 118, acts on a diaphragm 105 and, in conjunction with an adjustable spring 115, lifts the " bleed " valve 110 to admit air to the chamber 15 through an aperture 113 and the port 55. Slower clutch engagement occurs when the throttle is gently opened on starting the vehicle in bottom gear than when it is more rapidly opened following a gear change. When the clutch is fully engaged, valve 65 lies below ports 66, 53, as shown in Fig. 3, the suction port 97 being masked by piston 58. Specification 405,775 is referred to.
